. NURSING BOTTLE.

Application filed January 14, 1927. Serial No. 161,058.

This invention relates to nursing bottles, and its principal object isto provide a safety, sanitary, efficient, and improved nursing bottle. i

Heretofore, therubber nipples of nursing bottles were attached to thebottle-necks by merely stretching and slipping the nipple over the neck,and while doing so the users lingers often deposited germs upon theinterior side of the nipple, with consequent danger to the infantshealth. Those nipples also frequently slipped o the bottleneck duringthe feeding, thereby causing annoying spillage, spoliation, wastage, anddepriving the infant of food. Foreign substances and impurities oftenfound in milk, frequently entered the nipple and were taken up by thefeeding, with consequent injury to the infant. Upon removal of thenipples and cleansing of the bottles, the latter were frequently leftopenthroughv lacky of sealing means, and gathered germs prior torefilling of the milk.

Among the objects of this invention, therefore, is the provision ofmeans for remedyf ing the above mentioned disadvantages.

Other objects and advantages will hereinafter appear. v

In the accompanying drawingsf'- Fig. 1 shows a nursing bottle of thisinvention, with the improvements thereof shown in cross-sectionalelevation.

Figs. 2 and 3 are cross-sectional elevations showing modifications ofthe improvements.

The usual nursing bottle 1 `isprovided at the extremity of its neck 2with a threaded portion 3. The nipple 4 is made ofthe usual moldedrubber film 5, thel lower portion 6 of which is slipped over and firmlycemented'to a nut 7 made of any suitable material, such as hard rubber,glass, celluloid, or composition. Said nut is provided with a tap 8which may be threadedover the neck-extremity 3 in the manner shown, andit may be threaded firmly against a gasket 9 which surrounds thethreaded lextremity 3 and rests upon an annular shoulder 10 that `formspart of the glass bottle-neck and is located at the base of the threadedeXtremity 6. The nut 7 is provided with a central tapped hole 11 intowhich vthreads the terminal 12 of a tubular strainer 13 provided with aplurality of fine perforations 14, whereby when the nipple is in themounted statel shown the strainer projects downwardly into thebottle-neck 2.

When using this nursing bottle, the infant feeds at the nipple 4 in theusual manner,y

and the milk filters vthrough the strainer 13 before entering the nippleand is thereby fed without danger of contamination which might resultfrom possbile limpurities ofthe milk. yAs the nipple is directlycemented to the'nut 7 and the latter is in turn screwed to thebottle-neck, any possibility of the nipple accidentally slipping oi fromthe neck is precluded. The threading of the nipplenut 7 against thegasket 9 produces a firm closure of the bottle, and any'possible leakageis prevented. It will be noted that the provision for detachment of thestrainer 13, by unthreading it from the nut 7,- permits thoroughsterilization of all the parts, as is regularly required for nursingbottles.

According to the modifica-tion shown in Figs.2, 3, the bottle-neck 2 isprovided at its extremity with an additional threaded portion 15 whichis of smaller diameter than the threaded portion 3 which receives thenipple, and the strainer 13 is provided with a hollow the portion 15,thereby securing the strainer to the bottle instead of to the nipple, aswas shown in Fig. 1. The nut 7 to which the nipple is cemented isthreaded over the portapped flange 16 which treads over sfo tion 3 andagainst the gasket 9 in the manner l described in connection withFig. 1. The tubular shell of the strainer 13 projects above the flange16, forming the portion 17 which is threaded. When the nursing bottlewith all of its parts are sterilized and the nipple is stored away, acap 18, Fig. 3, may be threade'dover the portion 17 in the manner shown,and the bottle may be thereby eiiectively sealed and itsinterior'maintain'ed in cleansed sterilized state untilneededfor'further use.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without other-s.
